3.4 Final Preparation of the Device
Firmly tighten all screws. Tighten all terminal screws, including those that are not used.
Caution!
Inadmissable Tightening Torques
Non-observance of the following measure can result in minor personal injury or prop-
erty damage:
The tightening torques must not be exceeded as the threads and terminal chambers
may otherwise be damaged!
The setting values should be checked again, if they were modified during the
tests.Check if protection, control and auxiliary functions to be found with the configu-
ration parameters are set correctly (Section 2.1.1, Functional Scope). All desired ele-
ments and functions must be set 21. Ensure that a copy of the setting values is stored
on the PC.
The user should check the device-internal clock and set/synchronize it if necessary,
provided that it is not synchronized automatically. For assistance, refer to the SIPRO-
TEC
®
4 System Description.
The indication buffers are deleted under Main Menu → Annunciation → 6HW5H
VHW, so that in the future they only contain information on actual events and states.
The numbers in the switching statistics should be reset to the values that were existing
prior to the testing (see also SIPROTEC
®
4 System Description).
Reset the counter of the operational measured values (e.g. operation counter, if avail-
able) under Main Menu → Measurement → 5HVHW (see also SIPROTEC
®
4 System
Description).
Press the (6& key, several times if necessary, to return to the default display. The
default display appears in the display (e.g. display of operation measured values).
Clear the LEDs on the front panel by pressing the /(' key, so that they only show real
events and states. In this context, saved output relays are reset, too. Pressing the /('
key also serves as a test for the LEDs on the front panel because they should all light
when the button is pushed. If the LEDs display states relevant by that moment, these
LEDs, of course, stay lit.
The green “RUN” LED must light up, whereas the red “ERROR” must not light up.
Close the protective switches. If test switches are available, then these must be in the
operating position.
The device is now ready for operation.
